It don't seems to me an interesting question. The products are not comparable. I use Mathematica for analytical/numeric one process dynamics not for complete flowsheet simulation (dynamic /stationary).
One thing is to solve a reactor dynamic (control) problem other is to simulate a complete refinery (reactor, distillation, etc.) with properties estimation (and data bank).
A lot of work must be done to put mathematica at that level.
I am very hopeful that this forum will be important to the Chemical Engineering teaching.
